這裏比較明顯由於DELETE FROM wri$_adv_sqlt_rtn_planWHERE這條sql語法不對，導致無法解析因此報了ORA-00933錯誤.
情景再現
手動執行以下調用SQL，會再次觸發該問題：
SQL> exec SYS.PRVT_ADVISOR.DELETE_EXPIRED_TASKS();
PL/SQL procedure successfully completed.
就是他！就是他！ 。。報錯如下：

證明該程序本身有問題，屬於oracle bug範疇，查詢mos發現相關Bug 26764561 : ORA-00933 IN SYS.WRI$_ADV_SQLTUNE.SUB_DELETE_EXECUTION
